Absence of magnetic evidence for superconductivity in hydrides under high pressure

JE Hirsch, F Marsiglio - Physica C: Superconductivity and its applications, 2021 - Elsevier
It is generally believed that magnetization measurements on sulfur hydride under high
pressure performed in 2015 [1] provided “final convincing evidence of superconductivity”[2] …

[HTML][HTML] Meissner effect in nonstandard superconductors

JE Hirsch, F Marsiglio - Physica C: Superconductivity and its applications, 2021 - Elsevier
It was recently pointed out that so-called “superhydrides”, hydrogen-rich materials that
appear to become superconducting at high temperatures and pressures, exhibit physical …

Intrinsic hysteresis in the presumed superconducting transition of hydrides under high pressure

JE Hirsch, F Marsiglio - arxiv preprint arxiv:2101.07208, 2021 - arxiv.org
Superconducting transitions in the absence of magnetic field should be non-hysteretic. Here
we address the fact that the drops in electrical resistance that have been interpreted as …
